SCREW 1/4 TURN (LOCK PIN) #05

A screw is a type of fastener, in some ways similar to a bolt typically made of metal, and characterized by a helical ridge, known as a male thread (external thread). Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and prevent pull-out.

A screw drive is a system used to turn a screw. At a minimum, it is a set of shaped cavities and protrusions on the screw head that allows torque to be applied to it. Usually, it also involves a mating tool, such as a screwdriver, that is used to turn it. Other examples include Phillips head screws and screwdrivers, and Allen hex screws and wrenches.

Urns are commonly used by hotels, caterers, casinos and convention sites for buffets, holiday gatherings, brunches, meetings, and other group events events. Within foodservice equipment and smallwares, an urn is a large metal container with a tap used for hot beverage preparation and service.
